How Books Are Organized

Agathos Books uses three different ways to organize books, and they’re easy to mix up. Each one is managed by a different person and serves a different purpose.

Categories Collections Tags
Who manages them Agathos Books (automatic) Library admins You
Scope Every book on the platform One library My Books
Examples Fiction, Theology, Biography “Pastor’s Picks”, “Kids Area” “book-club-2025”, “gift-from-mom”
Where you see them Library rails (one library or all of them), filters Collections strip on a library page, filters Filters (My Books, Library), book detail
Can you create them? No — assigned automatically Only library admins Yes — anyone, on your own books

Every book on Agathos Books is automatically classified into broad categories like Fiction, Theology, or Children’s based on its metadata. You don’t tag books yourself — categories are how the platform groups books for browsing and discovery.

Use categories to find books. See Browsing by category for details.

Collections are curated groupings inside a single library, like “Pastor’s Picks” or “Kids Area.” A library admin creates them and assigns books to them, and they show up on the library page so members can browse them at a glance.

Collections live in one library at a time — the same book can be in “Pastor’s Picks” at one library and not at another. See Browsing library collections for details.

Tags are your own personal labels on books in My Books. Only you see them, and you can use anything that’s useful — “book-club-2025”, “gift-from-grandma”, “to-donate”. They’re great for short-term tracking and personal organization.

See Using tags for details.
